Umm, no.
Lisp is imperative, just like C. You can, by avoiding any side effects,
write functional programs with it, however, you'd have to avoid quite a few
of the built-in functions of common lisp, such as setf. Logic programming
and constraint logic programming are not available as paradigms of common
lisp, unless you extend the language (e.g., Screamer adds non-deterministic
backtracking). Certainly, there is no way, absent extensions, for me to
assert that
> (< X 37)
T
> (> X 35)
T
> (THE X INTEGER)
T
> X
36
in fact, the first assertion there would have just given me an unbound
variable error.
That there are multiple extensions to Lisp that can give me an embedded
language that will do these things is beyond question, however, none of
these things "are Lisp" unless we lose what we mean by "Lisp" - we
essentially claim the entire closure of all programs that can be written in
Lisp are Lisp too (and thus C is Lisp, UNIX is Lisp, COBOL is Lisp,
Microsoft Windows is Lisp, etc.)
